Question 2: When will longan mature? The maturity of longan varies with region and variety. Usually, the maturity of longan in Thailand is in late May. Guangzhou longan ripens in mid-July; The maturity of longan in Guangxi is from early July to early August; The maturity of Fujian longan is from late July to late August. In addition, the maturity of different varieties is also different. For example, the excellent variety "Yanfu" matures from late August to early September; "East Wall" matured in late August; "Wulongling" matured in September; "Songfengben" matured in late September-65438+1early October; "beginning of winter Ben" 65438+ 10 matured in late October. . . . . Hehehe, hope to adopt it. . .
Question 3: At what altitude is Yunnan longan suitable for planting? There is no requirement for altitude, mainly in terms of temperature. This area is also the species distribution area of longan, so Yunnan should pay attention to temperature selection.
Growing habits:
Wild or semi-wild in sparse forests.
Longan is a subtropical fruit tree, which likes high temperature and high humidity. Temperature is the main factor affecting its growth and results. Generally speaking, longan can grow and develop well where the annual average temperature exceeds 20℃.
Drought resistance, acid resistance, barren resistance, no soaking. It grows well in red soil hilly land and dry land, is easy to cultivate, has long service life, high yield and great economic benefit, and people like to plant it.
Distribution range:
Longan is native to the south and southwest of China. Now China longan is mainly distributed in Guangdong, Guangxi, Fujian, Taiwan Province and other provinces (regions). In addition, Hainan, Sichuan, Yunnan and Guizhou provinces also have small-scale cultivation.
Longan is planted in Thailand, Vietnam, Laos, Myanmar, Sri Lanka, India, Philippines, Malaysia, Indonesia, Madagascar, Queensland, Australia, Hawaii and Florida.
Training points:
First, seedling propagation is used to cultivate rootstock seedlings, and then grafting propagation is used.
When longan matures in July and August, the seeds will easily lose germination ability if the parent tree with strong adaptability, easy growth and less pests and diseases is selected. Seeding immediately after seed collection can improve the germination rate of seeds.
Sowing or drilling as required, the row spacing is 20cm, and the sowing amount per 1hm2 is about 750kg.
After sowing, the soil should be kept moist. When the height of seedlings exceeds 25cm, the top should be removed to promote the trunk thickening, and the base branches should be cut off at any time to keep the trunk smooth and upright at 10- 17cm. Through grafting operation, rootstock seedlings cultivated for 1-2 years can be grafted.
April-June in spring and September-65438+1October in autumn are suitable for grafting. Scions should be selected from the identified excellent mother trees. The grafting method is bud grafting or tongue grafting.
It can be planted in spring and autumn, mostly in rectangular or square shape. The planting row spacing is generally 4m, which is suitable for about 1hm2600 plants.
The management of annual trees should pay attention to intercropping and covering, reaming and soil improvement, timely fertilization and reasonable shaping and pruning to form a good tree shape and cultivate strong backbone branches. Adult trees focus on fattening, soil cultivation, farming, irrigation and pruning.
Question 4: When will longan mature? The flower bud differentiation of longan is closely related to heading, which generally occurs in February-March every year, and the pollination and fruit setting of longan generally occurs in late April to mid-May every year. Every year from the end of May to the end of August is the fruit-bearing growth period of longan, which is the key period to form the yield. Pick the fruit when it is ripe and yellow-brown.
Question 5: What month does longan mature? Longans planted in different areas have different time to market. The earliest longan listed in China is Hainan Longan, which was listed in March and ended in July. Longan in Guangdong and Guangxi began to be listed in June, and it didn't end until June 10.
Remember to adopt
Question 6: When will longan mature? The maturity of eyes varies from region to region and from species to species. Usually, the maturity of longan in Thailand is in late May.

Question 7: When is longan ripe and when is it not? Generally mature in July and August.
Question 8: When did longan mature? Longan is longan ... Longan is dried longan, which ripens in summer ... To be exact, it just ripened during our summer vacation ... Then my senior sister who spent the summer vacation at school said that she often stole from trees outside and ate at that time ... It seems that July should be the mature peak season, but litchi and longan are harvested every other year, that is, there is a bumper harvest every year. ...
Ps: I am studying in Nanning. I wonder if longan ripens early in other tropical areas?
Question 9: When will longan ripen? Longan is a southern fruit, which usually ripens in June and July. Of course, many of them are cross-season now. In Nanning, the ripening order of common fruits is: Myrica rubra in March, Plum in April, Loquat in May, Plum in June, Longan in July, Persimmon in August, Grapefruit in September, and 10 orange.
Question 10: When will the longan ripen? Longan (longan) matures in August-September, and early-maturing varieties mature in June-July.
Longan, also known as longan, is warm and sweet, benefiting the heart and spleen, and replenishing qi and blood; Has good nourishing and nourishing effects, and can be used for treating insomnia, amnesia, fright, dizziness and other symptoms caused by deficiency of both heart and spleen and deficiency of qi and blood.
It can also be used to treat weakness or mental decline after illness. It is also suitable for women's postpartum makeup. Li Shizhen recorded in Compendium of Materia Medica that litchi is the most expensive food and longan is the best resource. I admire longan more.
Pharmacological research shows that longan contains many nutrients such as glucose, sucrose, vitamins A and B, among which protein, fat and various minerals are more.
These nutrients are very necessary for the human body. Especially for hard-working people, it is more effective to consume sad temper and blood.
The maturity is in August and September, and the early-maturing varieties are in June and July.
